STUDY OF SUPERFLUID ィイD13ィエD1He FILMS BY 2D ELECTRONS AND 3rd SOUND

This is a pioneering study of superfluid I D13 ii D1 He films with employing such highly sensitive probes as 2D electrons on the surface，ions underneath the surface，hydrogen atoms adsorbed on the surface，and 3rd sound which propagate ove the superluid He film.Active collaboration between the leading research groups over the world in the field.So far，the results are mainly conserning the properties of superfluid y D14齐亚D1He films，those should be readily applied for superfluid齐伊D13齐尔D1He Those are nonlinear transport of 2D electrons on the He surface，transport properties of 2D electrons on superfluid；Ion mobility measurement beneath I D13文件D1 He surface.Exchange of expertises carried out very efficiently.The colaboration program has made a good basis for the future expansion of the research.
